Used as a catalyst in organic synthesis, particularly in bromination and oxidation reactions. It serves in research settings for the development of vanadium-based compounds and coordination chemistry. Also employed in the preparation of other vanadium salts and in studies related to magnetic properties due to its paramagnetic nature. Its reactivity makes it useful in transferring bromide groups in specialized chemical transformations. Vanadium(III) bromide is air- and moisture-sensitive, requiring handling in inert atmospheres or controlled environments.
